Answer:
isnt it 15
Step-by-step explanation:
since cold is vertical and vitiman c is horizantal you have to find where both number are or in other word where they stop
We would have to use the formula y1 - y2 / x2 - x2.
-5 - 3 = -8
2 - 6 = -4
Now we have -8/-4 and now we simplify to get 2/1
sense the formula of a line is y= mx + b we now how the first part which is
y=2x+b
now we can plug in the plot from the original points to the equation to finsish the problem
3= 2 x 6 + b
6 divided by 2 is 3 and 3 times -3 is -9 so the final answer will be
y=2x-9
So basically its arithmetic sequence cause u keep on adding 3
Rule: an=a1+(n-1)d
12+(20-1)(3)
Answer : 69
Step-by-step explanation:
<em><u>solve:</u></em>
<u>Subtract 2 from both sides</u>
=6x+2=2x+10
=6x+2-2=2x+10-2
<em><u>Simplify</u></em><em><u>:</u></em>
<u>Subtract the </u><u>numbers</u>
=6x=2x+8
<u>Subtract 2x from both sides</u>
=6x<em>-2x</em>=2x+8<em>-2</em><em>x</em>
<u>Simplify</u><u>:</u>
<u>Combine like terms</u>
=4x=2x+8-2x
4x=8
<u>Divide both sides by the same </u><u>factor</u>
4x=8
4x÷4=x 8÷4=2
<em>ANSWER</em><em>:</em><em> </em><em> </em><em> </em><em> </em>
<em>x</em><em>=</em><em>2</em>
The possible problems of using graphs to find roots are:
- Having complex roots.
- Having irrational roots.
<h3>How to find the roots of a quadratic function with a graph?</h3>
First, the roots of a quadratic function are the values of x such that:
a*x^2 + b*x + c = 0
To find the roots using a graph, we need to see at which values of x does the graph of the parabola intercepts the horizontal axis.
<h3>What are the possible problems with this method?</h3>
There are two, the first one is having irrational roots, in that case, an analytical or numerical approach will give us a better estimation of the roots. Finding irrational values by looking at the intercepts of the graph can be really hard, so in these cases using the graph to find the roots is not the best option.
The other problem is if we <u>don't have real roots</u>, this means that the graph never does intercept the horizontal axis. In these cases, we have complex roots, that only can be obtained if we solve the problem analytically.
